Post From: Sierra v2875 crashing with c_EncryptionIOBuffers memory error

About 1 in 30 startups, Sierra v2875 is crashing. ie. it closes and disappears off my screen. It starts up, looks normal, then within a few minutes it just disappears.

This started happening in the last few versions. Roughly since December but I don't have an exact timeline.

These are the last few messages in the logs:
2026-02-07 16:56:07.675 | HTTPS connection ID:2 to downloads.rithmic.com:443 for request ID:2 (6) | Creating socket. Using TLS 1.2.
2026-02-07 16:56:07.676 | HTTPS connection ID:2 to downloads.rithmic.com:443 for request ID:2 (6) | c_EncryptionIOBuffers memory error.
2026-02-07 16:56:07.677 | HTTPS connection ID:2 to downloads.rithmic.com:443 for request ID:2 (6) | CloseSocket call.
2026-02-07 16:56:07.677 | Rithmic Direct - DTC | HTTP response receiving connection points not completed or OK.

The only other thread I see related to this memory error is from 2022: Denali not streaming

Not sure where to start looking on resolving this.
