Transactions hanging - not clear why - ThCPICFree comm entry "without conv_id"

Former Member

Hi all,

I have a strange issue with a SAP 7.41 ABAP system

We can logon but many (not all) transactions hang with no clear reason why

Including check of remote TMS systems and recursive RFCs to the local system

The ORACLE archiver isn't stuck

No Linux file systems are full

The only trace of an error I can find is in the WP dev trace file in the "work" directory for this instance.

The repeating messages are like this:

A  StartDynpActionAfterRabax: start action 5

M  *** WARNING => ThCPICFree: comm entry 11 of T5_U29460_M0 without conv_id

Has anyone seen similar? You can also see the odd timeout. I'm wondering about storage access issues because I cannot see any clear indication of an issue in here

Hi Jamie,

Did you check the gateway trace  ?

Use transaction SMGW, Go to -> Trace -> Gateway -> Increase level.

Do it for sometime and check the logs.

Also, can you supplement the thread with TIMEOUT error that your are facing ?

Hi Divyanshu,

We will restart this system - then if still facing issues I'll try your good suggestion to trace the Gateway at a higher level. The timeout is in several functions - - SM59 RFC tests, STMS config distribution, SUPER user logon process, SMGW.... so indeed possibly Gateway/RFC/CPI related

Hi all - well it seems this was related to storage issues.

The Linux team apparently fixed some storage issues last Friday but the SAP layer wasn't fully restarted. Ran a full restart and now it's AOK. Thanks for the comments.

Hi,

Kindly refer SAP Note 1351096 - Hanging debug process fills file system

Thanks, but this note only applies to kernel 711 to 720 (we are on 740_REL)

Also it does not reference the message about "without conv_id" that I keep seeing

"ThCPICFree: comm entry 11 of T5_U29460_M0 without conv_id"

Hi,

Kindly share your system kernel level,if possible try to patch or upgrade with latest available and check for the results again.

In addition please share SM21 and dev_w0,dev_disp  log files for analysis.Meanwhile kindly refer SCN thread

Hi Gaurav,

This is a NetWeaver AS ABAP system on 7.40 SR1 (AKA 7.41)

The kernel is 741_REL patch 19 (Jan 2014)

Our other systems on this kernel do not have this issue and we aren't keen to mess with the kernel as the first step.

I cannot post whole logs here but here are key error message types from dev_disp and WP dev traces - however they are mainly timeout related and don't seem to give an RCA indication to me:
