Symptoms

In ProTrace, PDU and PDU decoding are not displayed for some given xDRs with "ERRlngth" error message on the PDU level.

Cause

Due to IDB synchronization issues, the impacted Build process starts using local UIDs to identify PDUs instead of extracting UIDs from master server. This leads sometimes to PDU overwriting.

Identify if this document applies

To identify this specific problem, check if the impacted Build process(es) logs include the following error message: "UIDs list is empty". To be able to check the logs of all build processes running on a given subsystem, follow this procedure:

1. Connect to any server of the subsystem and change the build processes logs level. As cfguser run:
   date;for j in `iqt -phz -f_name DaqServer | sort`; do echo "******** $j ********"; ssh $j "for i in \`igrep -pzh -fID -fServerID -fTypeID \\\`hostname\\\` Process | grep IxpBuild | cut -f1 -d\" \"\` ; do igrep -pzh -fProcessID -fName \$i DFlowProcessing; tr.setmask 0x7 IxpBuild\$i.PDM; done"; done
    
2. Extend the size of build logs' files to 10M: As cfguser run:
   date;for j in `iqt -phz -f_name DaqServer | sort`; do echo "******** $j ********"; ssh $j "for i in \`igrep -pzh -fID -fServerID -fTypeID \\\`hostname\\\` Process | grep IxpBuild | cut -f1 -d\" \"\` ; do igrep -pzh -fProcessID -fName \$i DFlowProcessing; tr.setsize 10M IxpBuild\$i.PDM; done"; done
    
3. Check if the error message is present on build processes logs. As cfguser run:
   date;for j in `iqt -phz -f_name DaqServer | sort`; do echo "******** $j ********"; ssh $j "for i in \`igrep -pzh -fID -fServerID -fTypeID \\\`hostname\\\` Process | grep IxpBuild | cut -f1 -d\" \"\` ; do igrep -pzh -fProcessID -fName \$i DFlowProcessing; tr.cat IxpBuild\$i | grep \"UIDs list is empty\"|tail -1; done"; done

If the command output look like following:

You have possible PDU display problem with STP2_SCCP_12, STP2_SCCP_13, STP2_MSU2_SUDR and STP2_SCCP_14.

Depending on build load, it might need time to ask next PDU file and for UIDs list is empty. Using local UID message to appear in log.

Solution

A temporary workaround consist of:

1. understanding root cause of IDB corruption and resolving it
2. restart IxpBuild process

PIC 9.0.4

For PIC 9.0.4: Install patch 20572849: Patch 5 for PIC 9.0.4" which include IXP 9.0.4-6.1.2.

PIC 9.0.3

For PIC 9.0.3 : System must be upgraded to 9.0.4 and then patched.

PIC 10.1.0

PIC 10.1.0 and above include the fix (no patch required).
