Bug Description
Try and execute:
$ cd /percona-server/5.5 # Containing bzr branch of 5.5.27 trunk
$ ./build/
$ cd ..; tar -xf Percona-
$ cd Percona-
$ mkdir /dev/shm/e
$ perl mysql-test-run.pl 1st
This consumes almost all server resources after a few seconds. Trying to launch another shell process gives 'Failed to fork (Resource temporarily unavailable)' on a high-end no-load freshly-restarted server. This is not the case on all these: Percona 5.5.25a, mysql 5.5.25a, mysql 5.5.27.
There is furthermore no output shown, even after some time. CTRL-C releases the resources immediately. No large memory or CPU consumption is seen while the process hangs. The OS settings on this server are increased already, so it is unclear atm which resource is being exhausted.
Fails:
- Percona-
Does not fail:
- Percona-
- mysql-5.
- mysql-5.
This also prevents RQG from working properly.
Workaround for RQG: see bug 1036506
