This can be done while vmtoolsd is running; the configuration change should take affect with in a few minutes.

Create a "guestInfo" section to the tools. Caution, there should be no trailing whitespace at the end of any line in tools. Hopefully the memory leak behavior has changed by this time. In reverse order, comment out the "guestInfo" directives previously added until the memory leak reappears.

At this point I am really interested in the vmware. The support bundle is 40 megs. Apparently the limit here is 10MB. I've attached the vmtools logs. I've been maintaining the open-vm-tools package for TC Linux for seven years so if this was an issue with previous versions I wasn't aware of it.

I only discovered this because it crashed a dhcp server which should be really hard to do. Everything seems to be as expected. I have filed and internal PR to reproduce the problem for further debugging and resolution. It's a squashfs archive. It is stored in the zip file so I could post it here. Apologies for the delay in response.

The tropical storms on the East coast last week has played havoc with internet access. Firstly, I have confirmed with our QE team that there is no memory leak detected in the current version of tools in development. I have also confirmed that open-vm-tools I left the vmtoolsd running for 3 days and collecting the process size every 2 minutes.

The testing was done on an ESXi 6. That suggests something specific to the open-vm-tools I was able to install TC I installed on WorkStation The problem is reproducible. I would also like to get a vmtoolsd core dump with symbols of a process exhibiting the memory leak. VMware has a couple of tools available that are aware of several memory management implementations and may be able to walk through the heap.

I has tried all the usual Linux tricks to enable and capture a core file, but have not been successful. This seems like something more efficiently discussed one on one, possibly through a Zoom session.

If you are agreeable to that, please contact me directly at. I've tried a few compiler options like Os vs O2, flto vs no-flto and some others but no change. GCC version is:. Please drop me a direct e-mail above when you have time and we can setup a mutually suitable time.

I am downloading a Leap In the meantime can you provide come additional information? Have you confirmed that it is the same memory leak. Create or add to the tools. By looking into the VM settings, please indicate: - number of disks and the disk device names - ide, scsi, SATA etc.

The fix for this issue has been checked into the "devel" branch at 81aff3a. This patch should apply directly to open-vm-tools A formal patch for those releases is being prepared and will be made available to Linux vendors. The comments for this patch say to free the memory before reusing it. What is the reason for not freeing it after we use it, so that it's not allocated while we not using it?

Maybe the comment should have ended in " Instead, the clean up of the GMatchInfo for early exits, as well as last use, is handled at the function "exit".

Thus a clean set of functions which can easily be modified, if needed, to:. Thanks johnvmw The issue was fixed in 25c2e Closing this issue. Skip to content. Star 1. New issue. Jump to bottom. Copy link. As a first step in identifying the source of the memory leak, please provide the following info: Version of open-vm-tools: Host and host version: ESXi, WorkStation or Fusion Linux guest: kernel version and OS release: Are you using open-vm-tools provided by the Linux vendor or user group or have you built open-vm-tools from the source release?

These answers will help determine the next steps to be taken to isolate the problem. Thanks for reporting this. Deleting plugin libguestInfo. That would not have been my first quess. The leak stops when I set this in tools. From the vmware-vmsvc-root. The frequency of size increases does not provide any hints to what may be the problem dealing with a single disk device, so the amount of memory used for each disk info iteration would be small. I would like to learn more about your open-vm-tools build: any TC specific patches in use - build or packaging any TC modified OSS packages in use.

If you are agreeable to that, please contact me directly at jwolfe at vmware dot com and we can set up some mutually agreeable time slot.

Thanks, John.
