Infopackage in process chain failing due to short dump on regular basis.

Question

HI Experts,
There is a daily process chain in which one of the element (infopackage) fails due to short dump on regular basis (At least twice in a week) please find the message below
Runtime Errors         DBIF_RSQL_SQL_ERROR
Exception              CX_SY_OPEN_SQL_DB
Short text                                                                               
SQL error in the database when accessing a table.
And in job log it is showing ARFCSTATE = SYSFAIL
We are able to resolve it just manual update and the process goes fine no issues but my question here is what is the exact reason for this and how to resolve it permanently or decrease the frequency of the error.
Please if any one can tell the root cause and the solution to avoid the issue in future on regular basis.
and also can any one elaborate what is ARFCSTATE = SYSFAIL,for trfc check we don't have access to SM58 in ECC side
and trfc is fine in bw side
Appreciate for not giving the general solutions like repeated solutions already posted in SDN
with regards,
musai

You can contact your BASIS person he can help you reg table space issue. it says used space is 98% and free space is 1.03%.
ask your basis to set a threshold to check the space and send a mail notification to all daily regarding the space allocation and utilization.
ARFCSTATE = SYSFAIL means the TRFC did not processed properly to the BW system from source.
Monitoring object with information about tRFC and qRFC calls that are waiting to be executed in this system; after they have been executed, they are deleted from table ARFCRSTATE.
Are there any hung TRFCs which are not processed to BW side. have you checked it
first check
load monitor -- menu -- environment -- job overview -- status of job(is it finsihed or not?) - check the job log -- ther try to find out the hung TRFc
press find --tyep "sysfail" ok -- it will display all the hung or fialed TRFCs which are not processed to BW system.
if you find the hung TID with respect to your load.. next goto SM58 trasaction to process the trfcs manually or use the load monitor menu -- environment -- transaction RFC -- source sys -- it will take you to same SM58 screen -- click F8 it will display the hung TRFc in that duration.
select the TRFc and click on F6 to process them manually.
also check the loackwaits anddead locks in ST04/DB6COCKPIT.( ask basis to check) if any dead locks are there they will take care of it.
check for short dumps in st22 if any and try to analyse.
Check the SM21 system logs.
