[sharp-discuss] Blank pages in SHARP again

[Derek Logan]

Hi Clemens and others,

I wrote quite some time ago about a problem relating to blank pages being served up by SUSHI from a SHARP installation on a Mac Pro (Mac OS X 10.6.7). The server is still running, but it simply shows blank pages. The only solution I know is to restart the httpd process. Unfortunately the problem has persisted and I have to do this restart several times per day if anyone is using SHARP.

SHARP is installed under the account "sharp" and there is for simplicity only one user, "derek". Well actually there is another one "marjolein", but she is using my account. The last few lines of sushi/logs/error.log read:

could not lookup DNS configuration info service: (ipc/send) invalid destination port

[Fri Apr  8 09:41:39 2011] [notice] Accept mutex: flock (Default: flock)

The last three lines derive from my restart. The question is which other lines are symptomatic of the blank pages problem? The Mac Pro is being a fixed IP address by a DNS server with which its MAC address is registered. Here come the last lines from access_log, from just before and after the restart. Does this give any clues?

Thanks
Derek
