disconnections

[Aqualung]

I have a question.
often my network breaks for short time and i see that the number of blocks for a long time remains unchanged. But as soon as I restart the program the number of blocks increases immediately.
Although the calculation of the blocks did not stop and i have "8 connections" all the way. So the question is - whether the blocks are generated during frequent disconnections? is the programm reconnecting automatically? or it's not necessary to download all blocks immediately as they created?
...hope you'll understand what i mean

Is your computers clock accurate?
What does the debug.log file say when it happens?

Generating blocks without being connected to the network is a waste of time because they will be never accepted by the network, they'll be too far behind when you reconnect.

There are lots of places you can check the current block number, but I like this one: ttp://nullvoid.org/bitcoin/statistix.php because it also has some nice graphs.

time is right +-2sec... or how accurate it should be?
there are many records in debug.log so i actually don't know what exactly matters
may be this...

And maybe program should stop calculating blocks when it losts connection to the network? Otherwise what that calculation for? Why it's possible to calculate whitout connection?
awesome image

rrrrrr! the problem is - i'm not recieving new blocks as soon as they created. why this stupid thing happens?

Do you get a new IP address after your Internet connection fails? That would cause your TCP connections to silently die. If that's the case, you might try enabling TCP keepalive in your operating system and setting a low keepalive time: maybe 10 minutes.

[Aqualung]

IP is always the same. There is a network with about 25 comps and with 1 static IP

[Aqualung]

looks like nobody knows how to help me
now i think it's not the disconnections causes problem... right now network is working quite well, but programm still don't want to download latest blocks... it waits for about 20-30 minutes and only then number of blocks increases immediately at 5 - 8 items... however, the generation does not stop for a second and i have 6- 8 connections all the time as i sad earlier. No errors in debug.log. Time was synchronized few days ago.

Are you running Microsoft Security Essentials? This sometimes blocks Bitcoin traffic.
Any other antivirus programs that may be filtering your traffic?

[Aqualung]

i have only Symantec Endpoint Protection and standart Windows XP SP3 firewall. After restarting bitcoin i'm getting all blocks... nothing blocks it... but few minutes later recieving stops.
why the program does not compare the total number of blocks created in the network and on each computer connected to this network?

[Aqualung]

well... i decided to reinstall bitcoin and found another problem)) When i started to download all the chain ones more it stops sometimes at 47501 or 52001 or 57501 or something like that and waits for... yeap... for restarting bitcoin... and then everything is ok for another 5-10 minutes... what the hell is wrong with my PC or with what??

It does some processing at that point that sometimes takes a while. You shouldn't restart it.

Try disabling your antivirus.

[Aqualung]

i have been waiting for a while, but... it does not help
i already tried to disable antivirus and firewall - same problem!
Only restart helps.  
socket recv error 10054 - was found in debug.log... what is it? Can this error cause my problem?
