Print process deadlock

Question

Hi All,
<br/>
<br/>We are now facing some problems on our smartform printing programs, sometimes some of the smartform programs look getting stuck, from SM50, the processing time is endless, and from the detailed tracing log, there are repeated messages like below for every ONE MINUTE:
<br/>I  WARNING: MtxLock 0x70000000636197c rrol0046 owner=33 deadlock ?
<br/>
<br/>I've searched the forum and also did google and SAP notes but can not get useful information match with my error, so could anyone please help to analyse what exact cause of this problem? Any suggestions is highly appreciated.
<br/>
<br/>The smartform program itself is simple and correct, just has one header and several items and uses normal SSF_FUNCTION_MODULE_NAME and CALL FNAME to do the print work, in most of time it works correct, but sometimes it just has problem and then the deadlock error occurred. I guess maybe it's because user tried to print too fast than the capability of the printer and then user canceled the job, then in some situations, the upcoming printing jobs get blocked and then get stuck, but it's just a guess, i've no proof to identify it.
<br/>
<br/>Here I attached the full trace log, hope someone could give me a idea, thank you very much!

Hi Sitarama,
<br/>
<br/>Thanks very much for your fast reply. Yes, the smartforms are custom-built. Besides the deadlock error, there still has some errors in SP01 says "Could not pass request to host spool system". But it previews wonderfully in SP01. The detailed SP01 error log is like below:

What do you mean parallel processing on table level? The smartforms extract data from different SAP tables and then transfer to smartform interface, then they can added in form pages. Do you think this results parallel processing towards tables?
<br/>
Thank you and hope to hear more from you.

Jeff
