Summary

0007822: Unix aio VM support for 1024+ descriptors

Description

The unix aio mechanism is limited to 1024 active file descriptors for sockets and file handles. For server application with many active socket descriptors, and for which the per-process descriptor limit has been increased above the default of 1024, this limit causes problems.

Additional Information

Reported by Göran Krampe:
http://lists.squeakfoundation.org/pipermail/vm-dev/2014-October/016648.html [^]

Reference to a reported fix described at:
http://lists.squeakfoundation.org/pipermail/squeak-dev/2003-May/057750.html [^]

Contact Ragnar Hojland Espinosa for the fix as per above link. Presumably this is Linux specific, so appropriate ifdef and Cmake control will be required.

Notes
(0014516 - 292 - 322 - 464 - 464 - 464 - 464) lewis 10-12-14 13:09	Levente Uzonyi adds this comment: I think this is a great summary of the current status on unix systems: http://daniel.haxx.se/docs/poll-vs-select.html [^] I think the best would be to use libevent or libev, but adding support for epoll (on linux only) is probably a lot easier thing to do.
