<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a job which runs on a host with ingres version II 10.2.0 (a64.lnx/100) + 15162.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It uses a vnode to connect to a database on another host which runs ingres version II 10.2.0 (a64.lnx/100) + 15151.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Having established the connection to the remote database it does some initial work and then must pause activity on that connection while work is being performed on other hosts/databases. After that work is completed the connection then
gets to do as follows:<o:p></o:p></p>
<p class="MsoNormal">drop table if exists targetable; /* Which works with no error */<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">create table targetable(<o:p></o:p></p>
<p class="MsoNormal"> a integer4 not null not default,<o:p></o:p></p>
<p class="MsoNormal"> b integer4 not null not default,<o:p></o:p></p>
<p class="MsoNormal"> c integer4 not null not default<o:p></o:p></p>
<p class="MsoNormal">) with nojournaling;<o:p></o:p></p>
<p class="MsoNormal">/* And this too works with no error. Note that the columns are all just plain old integers. Nothing fancy No blobs No nvarchar.<o:p></o:p></p>
<p class="MsoNormal">*/<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">copy table targetable(a=c0tab, b=c0tab, c=c0nl) from ‘a/raging/great/data/file’;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And on that last step we have recently started getting an error:
<o:p></o:p></p>
<p class="MsoNormal">E_LC0030_WRITE_SEND_FAIL GCA protocol service (GCA_SEND) failure with message type GCA_CDATA.<o:p></o:p></p>
<p class="MsoNormal">Internal service status E_GCfe06 -- Write to peer process failed; it may have exited. - System communication error: Connection reset by peer..Exiting session because of communications failure.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the errlog on the target installation we see:<o:p></o:p></p>
<p class="MsoNormal">biota ::[39831 IIGCC, 13193 , 0000000000000002]: Thu Sep 14 13:15:24 2017 E_GC2820_CONN_FAIL_INFO Connection to node '::ffff:10.131.0.3', port '59824' for user 'ingres' failed: reason follows.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have managed to show that this is a weird ass timeout. The jobs pause has now breached 15minutes (where have I seen that number before). The really curious thing is that the connection is perfectly fine with anything other than a copy.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m working on a test case at the moment, but as it relies on a very large data file it’s a bit of a nuisance.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anyone seen anything like this before?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
