We have again problems with our shared-memory area in xmid. It looks like php is not able to defend multiple write actions to the same mem-area at the same time.
We are working on a solution, but until then you can "reset" the shm-part of apache by:
1. ssh into reported xmid web-server 2. sudo ipcs -m | grep apache will return something like: 0x41400290 1 apache 666 20480 0
0x41400068 4 apache 666 20480 0 for every row: 3. ipcrm -M "shm-block" root@web01.app /dev/shm # ipcrm -M 0x41400290 root@web01.app /dev/shm # ipcrm -M 0x41400068
4. success!
Afterwards accounting should work until next crash (:
See you, Felix
