Occasionally, someone asks whether Solaris is an adequate platform for Zope/ZEO deployment.
Up to now, I answered to those questions -- we are using Solaris in our backend and up to now we did not see problems. This changed a few days ago -- we met an incredible limitation in Solaris: the number of "File" streams is limited to 256 in 32 bit applications.... This limitation caused us ZEO restarts once or twice a day since several days (with a completely stupid error message EAGAIN from "fdopen"). The problem is described in http://blogs.sun.com/mandalika/entry/solaris_workaround_to_stdio_s Don't use Solaris for Zope/ZEO, unless your are willing to deploy it as a 64 bit application (which we will try with our ZEO) or you are using at least Solaris 10 update 4. Watch out for "EAGAIN" exceptions from "fdopen" or other file creation functions. They indicate that Solaris has hit its 256 "File" limit.... -- Dieter _______________________________________________ Zope maillist - [email protected] http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
