Peng,<br>
Reliably reproduced here. Thank you for the minimal test case. This<br>
helped my investigation a lot.<br>
<br>
Usama,<br>
I have looked in to this a little bit and I have doubt in following<br>
code fragment (src/main/pgpool_main.c around line 1981)<br>
<br>
if (pid == process_info[i].pid)<br>
{<br>
found = true;<br>
/* if found, fork a new child */<br>
if (!switching && !exiting && restart_child &&<br>
pool_config->process_management = PM_DYNAMIC)<br>
<br>
Shouldn't this be as following?<br>
<br>
pool_config->process_management != PM_DYNAMIC)<br>
<br>
After this modification, all regression tests passed.<br></blockquote><div><br></div><div><a class="gmail_plusreply" id="plusReplyChip-2" href="mailto:ishii@sraoss.co.jp" tabindex="-1">@Tatsuo Ishii</a> Thanks for pointing this out.
