Hello, I recently moved from 389 to RHDS. The system is 32 bit RHEL5 with 4GB of RAM. My instance of RHDS recently stopped suddenly. The error log shows the following.. [17/Apr/2010:22:28:27 -0700] memory allocator - calloc of 1 elems of 10664 bytes failed; OS error 12 (Cannot allocate memory) The server has probably allocated all available virtual memory. To solve this problem, make more virtual memory available to your server, or reduce one or more of the following server configuration settings: nsslapd-cachesize (Database Settings - Maximum entries in cache) nsslapd-cachememsize (Database Settings - Memory available for cache) nsslapd-dbcachesize (LDBM Plug-in Settings - Maximum cache size) nsslapd-import-cachesize (LDBM Plug-in Settings - Import cache size). Can't recover; calling exit(1). I have used FDS/389 for nearly 2 years and had not encountered this error so not sure where to start. The settings for the above mentioned parameters(cachesize,cachememsize,dbcachesize,import-cachesize) are identical to the setting on my instances of FDS/389. I am assuming these are the defaults and are not the cause of the problem. I read this thread http://osdir.com/ml/general/2010-04/msg00801.html This thread mentions having your nsslapd-cachememsize large enough to hold your db in memory. I don't know if this is relevant or not.. I do remember seeing that Fedora dynamically increased cache sizes on my boxes with FDS/389 instances in the past. I am not sure if RHEL does the same or if that is the issue. My nsslapd-cachememsize is set to .. nsslapd-cachememsize: 10485760 My id2entry.db4 sizes for each of my 3 DBs are.. 40MB, 22MB, and 6MB.. Is there some way to help me to identify what may have caused the issue? Perhaps a setting on RHEL5 as opposed to Fedora needs to be tweaked or set as far as the OS is concerned. My package info is below. Thank you Name : redhat-ds-admin Relocations: (not relocatable) Version : 8.1.0 Vendor: Red Hat, Inc.
