OAS 4.0.8.1 wrkfs processes aplenty

Question

I have installed OAS 4.0.8.1 on Slackware 7.0, and it starts ok (using Netscape and the node manager listener), serves static pages as well as PL/SQL pages from a remote database, but the wrkfs process uses 100% of the cpu, and every few seconds another wrkfs process is spawned, and it uses as much cpu as it can get, until there are over 50 such processes. I then have to shut it down before it crashes the system. Using Netscape works to shut it down cleanly. How do I stop this in the first place?

Answer 1

My experience with wrksf, on Mandrake 7.0 (RH 6.1+) is that wrksf starts at first, then bails after about a second.
I have a couple cartridges installed, C and Perl, and it starts those cartridges up and then fails. I don't get the same error message that you do, but there is an error in the wrb.log:
`OWS-10911: Throwing exception for reason: wrkpGetProperty 2 `
`OWS-04793: Operation oracle_OAS_System_CartridgeServerFactory_create_nwreturns exception IDL:omg.org/CORBA/UNKNOWN:1.0 `
I'm not sure what this is all about, but it does start up my cartridges at first, because I specified a mininum number to start up initially, and a minimum number of instances.
They just don't come back if terminated, since wrksf isn't there.
BTW, this is the same error I encountered when, on NT, I compiled a c cartridge with Metroworks CodeWarrior instead of MS Visual C++ v6.0. So I wonder if this has something to do with compiler incompatibility, if wrksf was compiled with a different compiler from the rest of OAS. While compilers don't usually matter for C, they do for C++, and all binaries and libraries must be compiled with the same compiler/linker to work together.
Just a stab in the dark.
