Information in this document applies to any platform.
The dm_oracle throws PIN_ERR_NO_MEM error and the system stops working.
By sending the signal USR1 to the dm_oracle, we noticed that the free heap memory keeps decreasing, until it first crosses the high watermark (which I understand is meant as a warning when the allocated memory exceeds the 80% of the available shared memory) and then uses all of it.
This is happening especially (but not only) during billing.
The shared memory size is already 1.25GB:
- dm dm_shmsize 1342177280
- dm dm_bigsize 134217728
The bigsize could be reduced, but it seems the dm_oracle is constantly eating up shared memory, so decreasing it would not really solve the issue.
