Description:
------------
given that 5.1.12 was runnign the same setups over weeks with no reloads it seems some optimizations in the new version reduced stability

APCu is heavily used here for all sort of short TTL caching

----------------------

first at morning one machine got flooded with the same error and i thought it maybe because around 7 MB is large and shm-size only 64 MB

'cl_cache::write_shm_private()' failed - key: 'cl_pri_37747663f4c5fbd3fc4173ab9ed1297e7d7fc4f5sap_portal_ws10_m013_0', length: '7683806', content: 'a:1:

----------------------

apc.gc_ttl = 600
apc.shm_size = 512M
apc.entries_hint = 35000

APCU-Size:  7,27 MB
APCU-Hits:  116630 (2.4/Sek)
APCU-Count: 1375

i can't imagine why that could happen even given that apcu suffers from fragmentation - not after a few hours when it previously did work over days under every load

cl_cache::write_shm()' failed - key: 'content_2_19_0', length: '4179', content: 'Array
