mcpd crashes on out of memory.
MCPD can run out of memory and crash. Traffic disrupted while mcpd restarts.
MCPD experiences a memory leak under one of the following conditions: - A tmsh command such as the following is run: tmsh reset-stats ltm virtual - The ASM or AVR module is provisioned. In both circumstances, the 'cur_allocs' for one of MCPD's internal memory allocation types generally increases and becomes very high (e.g., millions): tmctl -I --select cur_allocs memory_stat program=mcpd name=umem_alloc_40
None.
A memory leak that occurred in the MCPD process has been fixed.
