Hi,


An error occured while running session ticpr2210m000 Calculate Cost Prise . it says WARNING: Running low on memory

and this error msg. is from log.bshell file :

plan6: Log message called from /port.6.1c.06.03/vobs/tt/lib/al_1/al_alloc.c: #2478 keyword: malloc
plan6: Pid 20704 Uid 137 Euid 137 Gid 125 Egid 125

plan6: Errno 0 bdb_errno 201 (Record changed after delayed lock)
plan6: Log_mesg: WARNING: Running low on memory
plan6: ******* E N D of Error message *******

this is the first time I see such an error . does anybody know the meaning of this error and why it happens.

extra information: the Calculate cost price session runs over 3 days .

Thanks

Caner,

You are probably running out of memory space in your UNIX kernel. Check the MAXDSIZE/MAXSSIZE/MAXTSIZE parameters and see if they need to be increased.

I have seen this behaviour 5-6 times in Baan environments at IVb, IVc and 5. The process takes an extraordinary amount of time, but when you look at the read rate for the driver, the number of reads per minute are very low. At the start of the process read rates are normal and progressively, it gets worse.

If you are having this type of symptom, it may be due to an application or driver memory leak. Eventually the process will hit the MAXDSIZE, MAXSSIZE, etc. boundary and the process aborts.

If you increase the max parameter you may see the same behaviour but it will take longer before the process aborts.

The key indicator for this problem is the decreasing rate of activity and the increase in size of the bshell. If this is occuring, there is probably an array or other similar construct that is getting too large or memory is not being freed up.

Yes I agree with the memory leak. I logged a Baan case for the
b4 product. Sessions that allocate mem do not free it up after.

What are the Database and OS/Hardware specs?

HP UX 11 B
4 CPU / 5 GB Ram

Informix IDS 7.31 FD.1

I still vote for the memory leak scenario I described above.

Are you able to see this performance characterization?

Any progress on checking the Baan objects for patches?

We too have seen this message once or twice during the last 6-8 months or so on our Baan IVc4/HP-UX 11.0/Informix 7.31.FC6/
Porting Set 6.1c.06.02 platform.
