Squid Fatal

<< < (2/4) > >>

Hi CharlieBrady

thanks for the below.

i think a fresh install will do good but for the time being it would be good to know what is actually causing the problem.

From Server Panel -> At Proxy Settings -> HTTP proxy status -> Enabled/Disabled

Enabled = the http service on the server slows to a point were websites doesnt even want to open (extremely delay). Google searches do though work quite well. The local network (file server side) also slows down extremely. HTTPS works fine.
Disabled = the system return to normal. HTTP service is fine and the local network access speeds up to what is expected.

From the trouble shooting the only item we found that failed or pointed to a failure is squid and subsequently this thread.

By your last message i understand squid isnt really handling this.

Is there anything else i can trouble shoot to find the problem for future instances/reference. All the logs are clean except for this error.

Kind regards

Maybe you have a slow disk problem.
Try this:

--- Code: ---[root@leopardo ~]# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   5556 MB in  2.00 seconds = 2780.14 MB/sec
 Timing buffered disk reads:  410 MB in  3.01 seconds = 136.14 MB/sec
[root@leopardo ~]#

--- End code ---

This show my HDD (a 1TB disk on 3Gbps controller).
If you have small values on second number (Timing buffered disk reads), maybe your computer aren't using DMA to disk access so they will be REALLY SLOW.

Hi Jader

Thank you for the advice.

i will try but the issue with the HTTP Proxy as explained is only something which has occurred recently.

the server itself have been operational now for +/- 5years. (gone through various hardware upgrades off coarse)

Kind regards

You said
"The issue arose after the system was shutdown without a proper halt due to power failures and our UPS failing. "

Charlie has suggested you test ALL your hardware including drives, memory etc (there is test software on sme to do these), or use an external test UBCD etc, have you done that ?

Anything could have become corrupted during that uncontrolled power shutdown & it is probably very hard to find.

Perhaps also delete the squid cache, search forums on
delete squid cache

Unless you have done all things above then there is no use to keep asking why do I have this problem.

Finally you were advised to rebuild the server from known good backups, but ONLY after testing all your hardware.
That is expert advice from one of the worlds leading experts on sme server, so it is probably the best overall approach to resolve your issue.

So get busy !

Hi Janet

Sorry for the late reply.

We have done the hardware testing (even changing of the memory at well as network cards, etc.) but still didn't have improvement and/or results.

We have decided that we will be doing a fresh install on the latest version on new fresh hardware were after we will migrate the configuration.

Also, my question was purely related to and for future reference - something to test, check, etc. I did state that the only failure/fault we are seeing in the logs are squid and the only setting we changed to resolve the lag was the HTTP caching. In future i will refrain from asking question for future reference as i see a person is treated as a retard that doesn't show (or deemed by others of not showing) respect when asking for assistance. Looks like saying thank you is a insult in today's world.
