Hi, Im having a problem where sapdb 7.3.30 memory usage jumps to around 1.8 GB and then it cannot get any memory from the OS (rc=8). OS is WIN2K From my understanding the memory used by sapdb is dictated by the datacache size (32000 or 256 MB) and max_sessions 500. (never seen this go above 400 MB totally for all connections) Can the sessions use unlimited memory. Under what circumstances will sapdb memory usage go above the configured sizes. Are then any other parameters dictating memory usage? This is the memory usage info from kndiag : 2004-02-10 01:43:14 0x370 19769 INFO Starting SERVERDB: 'MMP' 2004-02-10 01:43:14 0x370 19770 INFO SERVERNODE: 'onserguj' 2004-02-10 01:43:14 0x370 19771 INFO Process ID: 1240 2004-02-10 01:43:14 0x370 19773 INFO Date: 04-02-10 2004-02-10 01:43:14 0x370 19772 INFO Owner: 'SYSTEM' 2004-02-10 01:43:14 0x370 19774 INFO Product suite: 'Terminal Server' 2004-02-10 01:43:14 0x370 19775 INFO Number of Processors: 4 2004-02-10 01:43:14 0x370 19782 INFO Fiber: 'NO' 2004-02-10 01:43:14 0x370 19776 INFO Max virtual memory: 2047 MB 2004-02-10 01:43:14 0x370 19777 INFO Total physical memory: 1023 MB 2004-02-10 01:43:14 0x370 19778 INFO Available physical memory: 771 MB 2004-02-10 01:43:14 0x370 19779 INFO Kernel shared data size: 278 MB 2004-02-10 01:43:14 0x370 19837 MEMORY 445 Pages allocated for SHAREDDYNDATA at 0x03BE0000 2004-02-10 01:43:14 0x370 19837 MEMORY 1127 Pages allocated for CONVERTER CACHE at 0x03F60000 the knldiag then just has a few thousands of lines like this: 2004-03-01 10:30:33 0x750 19651 CONNECT Connection released, T83 2004-03-01 10:30:33 0x750 19633 CONNECT Connect req.
