When using any Symantec Endpoint Protection (SEP) 12.1 release, on 32-bit Windows systems, ccSvcHst.exe might crash due to a memory allocation failure. This may or may not involve trident.dll (our CMC TridentEngine) –the example error message below is for those cases that match the presence of trident.dll only.
In a WOW64 environment, ccSvcHst.exe is limited to 2 GB of virtual addressing space. For any process on the very edge of its virtual memory address space usage, additional memory allocations might fail and could lead to a crash if not dealt with appropriately. While most crashes will occur in this specific context, improper exception handling might lead to a crash even when the virtual addressing space limit is not reached.
This issue was resolved in SEP 12.1 RU6 MP8 and 14 or higher, by adding proper exception handling when a memory allocation fails for a number of specific scenarios to ccSvcHst.exe.
If an immediate upgrade is not an option, you may find that disabling Tamper Protection provides temporary relief.
