[squid-users] Squid 2.4stable1 crashes (2)

I don't know why, but I didn't see my post, though I sent it half a day ago.
Here it is again, please e-mail me any existing replies, in case my e-mail
server was down or so?
_________

Today, my Squid (Squid 2.4stable1) began to behave very strange. It was
running OK in the past.

What are the problems (as seen from the browser)? It doesn't finish loading
pages/pictures, loads only half of them, sometimes doesn't load them at all.

My Squid also crashed lately, so that I had to start it again.

I didn't make any changes in its config lately.

What may also help to identify the problem:
RH 7.0, 2.2.16-22 i586 (100Mhz), 16 MB ram, 210 MB swap.

When Squid was working OK:
- RAM practically full,
- swap usage - 23-25%, all the time.

When Squid began to behave strange:
- RAM also full,
- swap usage dropped to 10% (it took just a few secs), and was betwen
10-15%.

Restarting Squid didn't help at all.
I had to restart the machine, because I couldn't find any solution.

When I use the web, syslog adds the entries, that I copied below.
My squid.conf is further at the very bottom, after the logs.
