Search Server–Main thread proc crashed on cmd …

I was recently asked what these errors mean (you may see them in the PortalStatus report, or the application event logs):

(16:25 Search Server) - TeaLeaf Search Server Ver: 7.2.12.7296 - Main thread proc crashed on cmd /serverstatus. See TLSrchSrv log. 
(16:19 Search Server) - TeaLeaf Search Server Ver: 7.2.12.7296 - Main thread proc crashed on cmd /wordlist. See TLSrchSrv log.
(16:18 Search Server) - TeaLeaf Search Server Ver: 7.2.12.7296 - Main thread proc crashed on cmd /wordlist. See TLSrchSrv log.

That is not an unusual error. Historically, we started seeing the Search Server “crash” about version 4.x. The developers ended up buttressing the SS service with a number of error recover routines. You are seeing one of them here. The SS is the gateway between the Tealeaf software and the CTREE database that stores the persistent session data service. It is also the heart of the communications between the different  servers and routinely sends very large messages around the network. Depending on what kinds of queries are running, the tealeaf user load, etc, the SS may “crash”, but the error recovery routines are really good about getting it right back up.

The SS logs can be opened, and you can look for the crash in the log. It will reference back to the command that caused the crash, and the user/IP address that issued the command. You can take that step if you want more information.  However, I usually ignore these errors unless they repeat multiple times a day spread across many hours. If the errors are systemic, then you should contact Tealeaf support to get to the root cause.
