[vijivignesh15112013-crypto]

Hi

server details
:
CPU - 8 core
RAM - 15 GB

We run the virtual user 8 with warehouse 50 and running the test for 30 minutes . it executed sucessfully .
But When we run the test for 3 hours we are getting the below error . We are using the latest HammerDB5.0

2025-11-10 23:09:52,670|INFO|benchmarking_automation.hammerdb_executor|Error in Virtual User 1: server closed the connection unexpectedly
2025-11-10 23:09:52,670|INFO|benchmarking_automation.hammerdb_executor|	This probably means the server terminated abnormally
2025-11-10 23:09:52,670|INFO|benchmarking_automation.hammerdb_executor|	before or while processing the request.

Could you please help on this ?

Hi, it looks like you are using a wrapper that is making the error message less clear. The whole error message the client received should look like this:
server closed the connection unexpectedly, This probably means the server terminated abnormally before or while processing the request.
So, this means that the server went away while you were running the test. If it worked for a shorter running test and stopped on a longer running test one possibility is that it ran out of space, if there is no room in the WAL directory this would cause the scenario you are seeing.
