Hi Everybody, Anyone had ever problems with a spinning/runaway diag process (rdbms instance, not asm) on 10.2.0.3 RAC / RH 4? > ls -altr *diag* ... -rw-rw---- 1 oracle oinstall 311506 May 10 2008 prorac2_diag_27727.trc -rw------- 1 oracle oinstall 1096 May 14 2008 prorac2_diag_13877.trc -rw------- 1 oracle oinstall 4985163676 Dec 3 10:27 prorac2_diag_29143.trc > tail prorac2_diag_29143.trc SKGXPSEGRCV: MESSAGE TRUNCATED user data 48 bytes payload 120 bytes SKGXPSEGRCV: trucated message buffer data skgxpmsg meta data header 0x0x7fbfffd948 len 48 bytes SKGXPSEGRCV: MESSAGE TRUNCATED user data 48 bytes payload 120 bytes SKGXPSEGRCV: trucated message buffer data skgxpmsg meta data header 0x0x7fbfffd948 len 48 bytes SKGXPSEGRCV: MESSAGE TRUNCATED user data 48 bytes payload 120 bytes SKGXPSEGRCV: trucated message buffer data skgxpmsg meta data header 0x0x7fbfffd948 len 48 bytes SKGXPSEGRCV: MESSAGE TRUNCATED user data 48 bytes payload 120 bytes SKGXPSEGRCV: trucated message buffer data skgxpmsg meta data header 0x0x7fbfffd948 len 48 bytes SKGXPSEGRCV: MESSAGE TRUNCATED user data 48 bytes payload 120 bytes SKGXPSEGRCV: trucated message buffer data skgxpmsg meta data header 0x0x7fbfffd948 len 48 bytes And here's top output: top - 10:30:14 up 202 days, 11:16, 4 users, load average: 2.87, 2.77, 2.78 Tasks: 369 total, 2 running, 367 sleeping, 0 stopped, 0 zombie Cpu(s): 24.3% us, 21.1% sy, 0.0% ni, 33.9% id, 19.2% wa, 0.0% hi, 1.4% si Mem: 16408900k total, 16379576k used, 29324k free, 176712k buffers Swap: 8388600k total, 677940k used, 7710660k free, 11023172k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 29143 oracle 25 0 10.2g 91m 36m R 99.9 0.6 65151:03 ora_diag_prorac2 31085 oracle 15 0 10.1g 1.3g 1.3g S 38.5 8.2 0:30.15 oracleprorac2 (LOCAL=NO) 6137 oracle 16 0 10.2g 818m 798m S 13.3 5.1 0:10.59 oracleprorac2 (LOCAL=NO) 2783 oracle 15 0 10.1g 2.6g 2.6g S 4.6 16.9 0:35.02 oracleprorac2 (LOCAL=NO) 14250 oracle 15 0 10.1g 2.3g 2.3g S 3.0 14.9 0:27.06 oracleprorac2 (LOCAL=NO) Killing the diag process just restarts it, and runs up to the high util again . ML search doesn't find anything, or any other searches. Any ideas? Thanks, Juergen Stegmair ENKITEC
