Description

I wrote to the mail list but no one answered. Hope this is the better place for such report.

I have one problem with updating the directories. Sometimes a server is dropping out of network for various reasons but still remains connected on welcome page. When I'm trying to access any directory my node starts map updating and it may be very long operation during which all work with directories hangs. It takes from 10 to 14 minutes and I guess it's unacceptable for such system. Where can I set the timeout for this? I set up:

timeout.keepalive = 60 timeout.disconnect = 300

But this doesn't help. One of servers lost internet connection suddenly and that's what I got accessing one of directories (there were 4 servers and only 3 requests succeded):

Started: 15:11:01 26-Jul-2010 Finished: 15:25:51 26-Jul-2010 Storage Index: o4wudooveaakzeqdhvspjsjgtm Helper?: No Progress: 100.0% Status: Finished Update Results

Timings: Total: 14 minutes Initial Queries: 4.5ms Cumulative Verify: 1.0ms Per-Server Response Times: [nfyml6h3]: 3.4ms [t726lxet]: 67ms [35jflwuq]: 32ms

Almost 15 minutes! That becomes critical if you mount a directory via sshfs+sftpd, then any process may stuck when lists this mounted dir and the only way is to kill sshfs (you couldn't kill the process itself, it's in D+ state) or wait (not knowing how long). Please, point me to the right timeout option for such requests! 10 to 30 seconds would be very nice.
