Hi Foo Could it be an application problem. It sounds like an application is adding data to a possible type 1 file as a log or a como file or even a print job and it is growing to an enormous size consuming resources. There might be some other application that has gone rogue. Can you identify the time this problem started and relate it to a program that was updated. Can you identify a user who is using a lot of the resources and find out what they are doing.

A bit intro on hardware specs. We are using pSeries 650 running on SMP 2 Power4 processor with 4GB of RAM, 4GB Paging size and RAID5 SSA Hard Disk. My Universe configuration as below: Current tunable parameter settings: MFILES = 300 T30FILE = 200 OPENCHK = 1 WIDE0 = 0x3dc00000 UVSPOOL = /uvspool1 UVTEMP = /uvtmp1 SCRMIN = 3 SCRMAX = 5 SCRSIZE = 512 QDEPTH = 16 HISTSTK = 99 QSRUNSZ = 2000 QSBRNCH = 4 QSDEPTH = 8 QSMXKEY = 32 TXMODE = 0 LOGBLSZ = 512 LOGBLNUM = 8 LOGSYCNT = 0 LOGSYINT = 0 TXMEM = 32 OPTMEM = 64 SELBUF = 4 ULIMIT = 128000 FSEMNUM = 23 GSEMNUM = 97 PSEMNUM = 64 FLTABSZ = 11 GLTABSZ = 75 RLTABSZ = 75 RLOWNER = 300 PAKTIME = 5 NETTIME = 5 QBREAK = 1 VDIVDEF = 1 UVSYNC = 1 BLKMAX = 131072 PICKNULL = 0 SYNCALOC = 1 MAXRLOCK = 74 ISOMODE = 1 PKRJUST = 0 PROCACMD = 0 PROCRCMD = 0 PROCPRMT = 0 ALLOWNFS = 0 CSHDISPATCH = /bin/csh SHDISPATCH = /bin/sh DOSDISPATCH = NOT_SUPPORTED LAYERSEL = 0 OCVDATE = 0 MODFPTRS = 1 THDR512 = 0 UDRMODE = 0 UDRBLKS = 0 MAXERRLOGENT = 100 JOINBUF = 4095 64BIT_FILES = 0 TSTIMEOUT = 60 PIOPENDEFAULT = 0 MAXKEYSIZE = 255 SMISDATA = 0 EXACTNUMERIC = 15 MALLOCTRACING = 0 CENTURYPIVOT = 1930 SPINTRIES = 0 SPINSLEEP = 10000 CONVERT_EURO = 0 SYSTEM_EURO = 164 TERM_EURO = 164 SQLNULL = 128 When the uv restarted it run fine for a day before it used up all the CPU and memory resources. A fast check on 'topas' show CPU resources used up for Kernel and User. There are no free resources on Wait and Idle. Around 70% of the CPU resources used for User and 30% used for Kernel. On memory side, seem all the physical memory had been consumed up. Even Paging space also been used. A quick snapshot on the memory from 'topas' as below: MEMORY Real,MB 4095 % Comp 22.4 % Noncomp 76.2 % Client 75.1 PAGING SPACE Size,MB 4096 % Used 1.4 % Free 98.5 When all the physical resources are fully occupied, the Universe processing become slow. The only thing I can do now is to restart Universe when the performance degraded? Are there any performance tuning we need to do on the OS to prevent this issue? Or is there any known issue with this version of Universe? Please assist me to solve this problem. Regard's, Foo --- Outgoing mail is certified Virus Free.
