@BAOX17175074 Yes, I think out of memory errors can definitely cause your server to drop unexpectedly. When the system runs out of available memory, it can’t handle new requests or processes, leading to crashes or shutdowns to protect the server. Since you noticed these errors after releasing a new function, it’s possible that the new feature is using more memory than before, perhaps due to inefficient coding or a memory leak where the program doesn’t properly release memory after use. To fix this, you should check the server’s memory allocation and ensure it’s sufficient for the new function. Also, review the new code for any issues that might be causing excessive memory use. Monitoring tools can help track memory usage over time to identify patterns or specific triggers. Additionally, updating Pega and other related software to the latest versions might include important fixes. Thanks
