PHP runs out of memory when creating complex templates

    Details

      Description

      I have a template, that has two parent templates with trigger dependencies between the parent templates. When I'm trying to import the templates from zbx_export_templates(3).xml PHP runs out of memory. I suspect this is caused by trigger dependencies.

      Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 41 bytes) in /opt/lampp/htdocs/zabbix/trunk/frontends/php/include/classes/debug/CProfiler.php on line 232

      After that the database becomes locked and an attempt to update something in the frontend results in errors like:

      Error in query [SELECT nextid FROM ids WHERE nodeid=0 AND table_name='hosts' AND field_name='hostid' FOR UPDATE] [Lock wait timeout exceeded; try restarting transaction]
