While performing the IRIS upgrade on our backup test server I noticed the following error in the messages log after restarting IRIS:

04/26/24-16:28:36:788 (5701964) 1 [Utility.Event] (HSHCPRT) Failed to retrieve journal file #9567 from FCHHSHCPRTTX02/PRT: Failed to allocate a 33686036 byte tcp buffer for zlib compress.

Stumped on this one, I logged a WRC and looked at some things with support but was not able to resolve the issue. Any help would be greatly appreciated.
