I am encountering an error condition when attempting to connect my local LoadRunner Controller to a remote Load Generator agent running on a Linux host.
The error occurs after I have been using the agent on the remote host for several months. That is, I am able to use the agent to run load tests successfully for a considerable amount of time (>150 days) until this error begins to occur. Once the error condition occurs, it will persist until the host server is rebooted. Shutting down and restarting the load generator software does not solve the problem. Whatever the root cause, it appears a reboot of the host resolves the underlying condition.
Here is what I think is the primary log message of interest:
Error: Communication error: An error occurred while trying to create mutex. (sys error message - No space left on device) [MsgId: MERR-10344]
I have checked a few things:
- All file systems have available space.
- System real/swap memory is available.
- I have attempted running strace against the process and while there are a few calls that return in error, a root cause does not stand out.
Here are a couple of host vitals:
Linux Host OS: RHEL 6.7
Load Generator Version: 12.02
Has anyone discovered a method to resolve this problem without having to reboot the host?
Thanks in advance. -Brian
