How often does the problem occur for you? Was this a single-time crash or it happens regularly and is easily reproducible?

Comment by Alexey Pustovalov [ 2011 Sep 22 ]

the problem occur for me only once. Single-time crash. Not reproducible. Settings not changing, but server working stable.

We think that this problem might or might not be related to ZBX-4151 - both reports are about corrupted heap memory. However, heap memory could become corrupted in any part of Zabbix server code, so investigating these issues without additional information is somewhat difficult. I propose we close this issue for now as "Cannot reproduce". Please reopen if a similar memory problem occurs again.
