RFC Jobs getting stuck

[Former Member]

All RFC Outbound jobs are getting stuck in my production system ,

The strange part is they are only getting stcuk in the App servers and not CI, InCI they are getting successfully completed .

When I goto SM66 the background WP corresponding to those josb are in Stopped status reason being CPIC ,

I even checked the RFC (Pointing to the database server) its fine.

Please advice

This is not the case .

Depending on system size you may need to increase the parameters

gw/max_sys - max. number of connected clients
gw/max_overflow_size - max. swap space for CPIC requests in a gateway
rdisp/wp_ca_blk_no - work process communication blocks
rdisp/max_arq - max. number of internal asynchronous messages

when i look at the gateway trace of the app servers i see the below mentioned error

• ERROR => R3ISearchPartner: timeout, partner LU: >BP1TULAP521<, TP:

>rfcexec< [gwr3cpic.c 5743]

• ERROR => R3ISearchPartner: HOST: BP1TULAP521.bp1.ad.bp.com, conv

ID: 45684584 [gwr3cpic.c 5756]

Please advise

The problem seems to be, that BP1TULAP521 doesn't answer in time and thus the RFC running into a timeout.

Are there maybe all workprocesses busy on that system when this error occurs?

The ping is working fine and so does the file system

The databse is Oracle 9.2 and SAP is 4.7 enterprise

The WP trace file shows

ERROR => BtcAuthSet: dy_signi-call failed, rc: 1 [btcjcntl.c 1025 ]

Can the receiving system also reach your application server?

Hello

Check if you have run out of space in any filesystem in the application server (/usr/sap/SID). Also check if any NFS mounts you have are working ok and if the hostname of your application server can be reached (try a ping). Also try to reach the application server via a ping from somewhere else.

Some extracts from sm21, and the developer traces of the work processes that are stopped (localed under /usr/sap/SID/Dxx/work) would help me tell you more!

What SAP version / OS / Database are you running on
