<main> <article class="userContent"> <h2 data-id="summary"><strong>SUMMARY</strong></h2> <p>Cold copy times may be unusually long due to unnecessary processes consuming appliance resources.</p> <h2 data-id="issue"><strong>ISSUE</strong></h2> <p>Cold copy times may be unusually long due to unnecessary bpserverd processes consuming appliance CPU resources. <br> </p> <h2 data-id="resolution"><strong>RESOLUTION</strong></h2> <p>To determine if you have this condition, you may check bpserver log history in /usr/bp./logs.dir. <br><br>Confirming this issue can be done if you see multiple log parts for a bpserverd process being created in quick succession, 0-1 seconds apart. Here's an example: </p> <pre class="code codeBlock" spellcheck="false" tabindex="0"> ls -rlast /usr/bp/logs.dir/bpserver-*_*.log -rw-rw-r-- 1 root loggers 10485854 Jul 24 11:44 bpserver-9_2.log -rw-rw-r-- 1 root loggers 10485847 Jul 24 11:44 bpserver-2_2.log -rw-rw-r-- 1 root loggers 10485854 Jul 24 11:44 bpserver-9_1.log -rw-rw-r-- 1 root loggers 10485847 Jul 24 11:44 bpserver-2_1.log -rw-rw-r-- 1 root loggers 7392888 Jul 24 11:44 bpserver-9.log -rw-rw-r-- 1 root loggers 8993669 Jul 24 11:44 bpserver-2.log</pre> <br>Further confirmation would require looking at the contents of these logs. If the value "SR: timed out [1]" is repeating through the log with high frequency, then you are impacted by this issue. here's an example: <pre class="code codeBlock" spellcheck="false" tabindex="0"> cat /usr/bp/logs.dir/bpserver-9_2.log | grep "SR: timed out [1]" 2017-07-24 11:38:18.115 -0500 : [LOG1] SR: timed out [1] 2017-07-24 11:38:18.115 -0500 : [LOG1] SR: timed out [1] 2017-07-24 11:38:18.115 -0500 : [LOG1] SR: timed out [1] 2017-07-24 11:38:18.115 -0500 : [LOG1] SR: timed out [1] 2017-07-24 11:38:18.115 -0500 : [LOG1] SR: timed out [1] 2017-07-24 11:38:18.115 -0500 : [LOG1] SR: timed out [1]</pre> <br>To resolve this issue, upgrade your appliance to version 10.1. <h2 data-id="cause"><strong>CAUSE</strong></h2> <p>Several different processes could result in a competing condition lending a bpserverd process to continuously poll for status decreasing CPU availability. This condition is rare but when encountered during a cold copy can impact backup or cold copy performance. <br>The resolution involves a combination of kernel update to linux as well as several Unitrends code adjustments. </p> </article> </main>
