Problembeschreibung: | |
This problem was reported on linux x86_64 running IDS 12.10.FC10 As part of APIM monitoring, they execute many queries against sysmaster:syssqlhosts. There appear to be leaking memory out of the global memory pool which can be seen accumulating in an 'onstat -g afr global' Many of these leaked blocks are like these: 467a0dd0 64 net 3457 osmutex.c:595 467a0e78 64 net 3457 osmutex.c:595 467a0f00 64 net 3457 osmutex.c:595 467ef978 64 net 3457 osmutex.c:595 467efa08 64 net 3457 osmutex.c:595 467efae8 64 net 3457 osmutex.c:595 46b4ce00 64 net 3457 osmutex.c:595 46bf5500 64 net 3457 osmutex.c:595 Which appear to hold the csm options field in the sqlhosts file per following mem dump of one of these blocks $ ifx onstat -g dmp 0x467a0dd0 64 address bytes in mem 00000000467a0dd0: c91bf48c 00000000 18005302 0000810d ........ ..S..... 00000000467a0de0: 100e7a46 00000000 780d7a46 00000000 ..zF.... x.zF.... 00000000467a0df0: 40000000 00000000 454e4343 534d0000 @.......
