After you restart your ICM service, you are getting below error trace,
*** ERROR => can't open directory '/usr/sap/SID/DVEBMGSxx/data/cache' [ictxxcache_r 4085] *** ERROR => IctCmCreateCache() failed rc=3 [http_cache_m 2157] WARNING: could not create disk cache. running with memory cache only ISC: created 50 MB memory cache.
Solution
As clearly mentioned in the dev_icm log file, the cache directory couldn’t be open! Possibility caused are maybe the cache directory is missing are not in correct permission. So, login to your operating system to create the cache directory or grant the correct folder permission. A restart of SMICM is needed to apply the change.
