<div dir="ltr"><div> Hi,</div><div><br></div><div>We found another leak related to monitor-method(poll). When the tracked directory is deleted, glib allocates a GError structure for "Error opening directory \'...\': No such file or directory", that was not freed by syslog-ng. This can cause considerable memory leak when high number of directories tracked and deleted. We created a pull request to fix it: here you can track the progress: <a

There is a race between file delete and syslog-ng reading the data. It can happen that one deletes a file before syslog-ng reads all its contents, which would cause message loss.

In my use case, new folders & files are created constantly under base-dir folder, but every 2 days obsolete folders & files are deleted. I assumed that syslog-ng would free some RAM every time those folders & files are deleted, but it doesn't, not even if I run a syslog-ng-ctl reload operation.<br></div><div><br></div><div>log-fifo-size value is 345000, so I assume it can't be a buffer situation since 345000 messages can't occupy 40-50 GB of memory.<br></div><div><br></div><div>I've performed the following test to reproduce the situation in small scale:<br></div><div><br></div><div>- Launch a syslog-agent with a wildcard-file source reading from "/tmp/test/" base-dir. syslog-agent RAM usage is about 125M.<br></div><div>- Run a simple script to create complex folder hierarchy under /tmp/test and some files with 5000 log messages to read from.</div><div>- Wait until syslog-agent RAM usage gets 1GB</div><div>- Stop script execution and wait until syslog-agent has send all logs to relay.</div><div>- Delete everything under /tmp/test and execute syslog-ng-ctl reload operation</div><div>- 24 hours after, syslog-agent RAM usage still is 1GB</div><div><br></div><div>I've used heaptrack tool as a try to find a memory leak in syslog-ng, you can see in the attached image that iv_list_empty function in iv_list.h file is where most of the RAM usage is.</div><div><br></div><div>How do I get syslog-ng to free RAM?
