Thank you for your reply.
The cause was a mismatch of character code.
Monitoring items on Zabbix Server had been set in UTF8.
but , monitored file was using the UTF16.
When monitoring items and monitored file are set in UTF8, Symptoms were improved. - no crash
1. Does the issue occur regularly?
If monitoring items is set UTF8 , monitored file is set in UTF16 and Proxy is monitoring 1000 LOG items, the issue occur regularly.
but monitoring items is set UTF8 , monitored file is set in UTF16 and Proxy is monitoring 1 LOG items, the issue doesn't occur.
2. Could you provide the build configuration (./configure script parameters) that you used to build Zabbix (proxy)?
I'm using the RPM package.
