Error Message
ERR_SHM: Shared memory error
Known Causes
4 known causesInsufficient System Resources
The operating system or SAP instance lacks sufficient physical memory or swap space to allocate the necessary shared memory segments.
Incorrect SAP Parameter Configuration
SAP profile parameters related to shared memory (e.g., shm_max_size, abap/buffersize) are incorrectly set, leading to allocation failures.
Operating System Limits
The underlying operating system's kernel parameters for shared memory (e.g., SHMMAX, SHMALL, SHMSEG) are too low for the SAP instance's requirements.
Corrupted Shared Memory Segments
Existing shared memory segments may become corrupted due to system crashes, improper shutdowns, or other underlying issues, preventing new allocations.
