DCR.Wait failed under Dyalog 17

Hi

Under Dyalog 16 I am not getting this problem.

Under Dyalog 17, after running my MiServer site for some 10's of minutes, I am getting several screen fulls of an error message, and then Dyalog crashes.

The repeating message is
#.DRC.Wait Failed:
1138 ERR_WORTHREADENDED Workthread have terminated

I have a 269,313KB APLCORE available from one such occurrence.

The MiServer version I am using is
3.0.1539 - (ffb00c39ac573a09245d36f31f48f93b62af7955)

I have tried running my site under
3.1.1603 - (fa25fd7f3cb5be4efe4d3634607bc8f20d2dc7cb)
but the AJAX code fails to start and so the site cannot be tested.

Any suggestions?

Hi Ray,

This issue may be related to the FIFOMode setting in Server.XML.
Can you either
  1. try setting FIFOMode to 0 or
  2. install MiServer version 3.1.1661
and see how that runs?

I'm also curious about the AJAX code failing. If it continues to do so under MiServer v3.1.1661, can you send me more information via email?

I hope this helps!

Thank you Brian for your quick response.

Setting FIFOmode to 0 caused it to fail with the same message within seconds, so no joy there.

I will try installing 3.1.1661 and let you know how I get on.

Thanks again for your help.
