A new logging feature is undocumented but available in 5.1.2. This logging will allow us to monitor large memory allocations due to large queries using GLEWF. The feature is enabled by setting 2 parameters in the ar configuration file.
Large-Result-Logging-Threshold: 90000
Debug-mode: turn on bit 6 (value 32)
Debug-mode can be set using the Admin tool by choosing the Thread logging.
After these parameters are set in the ar configuration file the ar server should be restarted or arsignal used to trigger a re-read of the file. The server will now log memory allocations used by GLEWF ARGetListEntryWithFields if the api requires a memory allocation (shown by Overflow memory) of larger than or equal to Large-Result-Logging-Threshold. In the following examples a query was run which requires a malloc of 88143 bytes of memory. The log entry is written when the malloc is larger than the configured threshold.
Large-Result-Logging-Threshold: 50000

Large-Result-Logging-Threshold: 90000

NOTE:
To sort the thread log in descending order of memory overflow size:
sort -r -n +18 [filename] | more
Hope this article helps you..

Hello, I installed the patch 18 for remedy 6.03 and we seem to be still
having memory issues. I was wondering if there was a way to log memory
allocations within the log files.
Any thoughts?
