Hi, we are using a MaxDB 7.6.00.16 on a dedicated DB-Server (Win 2003 Server, 2 Intel XEON, 4GB RAM, 500 GB Diskspace).
>From time to time the kernel crashes. We believe that the crach is influenced by the values of the following parameters: MAXUSERTASKS = 500 CACHE_SIZE = 100.000 _CAT_CACHE_MINSIZE = 262.144 In former times we've computed CAT_CACHE_SUPPLY in the following way: (MAXUSERTASKS + 1) * _CAT_CACHE_MINSIZE = 131334144. In the hope to solf our problems we increased this parameter to 190000000 Below is a snippet from knldiagerr: ---------------------------------------------------------------------------- ---- Date Time TID(hex) Typ MsgID Label Message-Text ---------------------------------------------------------------------------- ---- 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY TransContext T429 : could not allocate 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY memory 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY required : 13765936 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY allocated : 134594560 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY supplement : 13766656 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY limit : -1 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY free blocks size 24 : 1 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY free blocks size 32 : 3 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY free blocks size 56 : 1 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY free blocks size 80 : 1 2006-07-17 11:36:33 0x1410 ERR 54008 MEMORY free blocks size 304 : 1 2006-07-17 11:36:33 0x1410 ERR 51080 SYSERROR -9407 unexpected error 2006-07-17 11:36:33 0x1410 ERR 1 Table Table_TempHashTable.hpp:759 2006-07-17 11:36:33 0x1410 ERR 1 Table 2006-07-17 11:36:33 Table Error 1 2006-07-17 11:36:33 0x1410 ERR 1 Table No sort array 2006-07-17 11:36:33 0x1410 ERR 1 Table + Table_TempHashTable.hpp:760 2006-07-17 11:36:33 0x1410 ERR 1 Table + 2006-07-17 11:36:33 Table Info 2 2006-07-17 11:36:33 0x1410 ERR 1 Table - Sort entries failed 2006-07-17 11:36:33 0x1410 ERR 1 Table + Table_TempHashTable.hpp:404 2006-07-17 11:36:33 0x1410 ERR 1 Table + 2006-07-17 11:36:33 Table Error 6 2006-07-17 11:36:33 0x1410 ERR 1 Table - Cannot determine first entry Thanks in advance for any help.
