segfaulting 11 after some perl module updates
Hi

After following perl module updates:

DBD-mysql-3.0000
Net-DNS-0.52
Time-HiRes-1.72
Sys-Hostname-Long-1.4

proxied mod_perl is segfaulting and hence cannot run gmail.
Anything realted with the above upgrades or is it some other reason?

Just a feedback:

I downgraded to DBD-mysql-2.9008 and immediately the problem disappeared. No more segfault (11) errors. This is just a feedback to see if DBD-mysql-3.0000 is in any way be causing this error.
backend is 1.3.31apache + mod_perl1.29
frontend is 1.3.33 apache + mod_proxy+mod_gzip + other cpanelstuff

Thanks

Nice find. I was just debugging a GLinks installation today that was segfaulting somewhat randomly and it looks like it also has DBD::mysql version 3.0 installed - probably also the same problem.

Another recent cpan goofup was Net::DNS (0.50/51) which broke network tests in SA 3.0.4 which worked fine by default till 0.48 so this lead of corrective action of a downgrade was an extension of the earlier experience with Net::DNS

Since it was a regular segfault on GMail (just allowed me nothing beyond just a login)i could "guess" that it had to be something related to upgrades.

I still see few big site admins still groping in the dark to this error:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /cgi/dirsearch.mp.
Reason: Error reading from remote server

Hmmm.... they should regularly visit GT forums :=) (though they are not on gt products)




Thanks

Hi

Here's the quick reply from the author on being contacted right now:
====
I think it pertains to an issue with using '"'s or "'"s in an insert or update. I'm working on a fix for it right now,

Thanks for the report!

Thanks

DBD::mysql 3.0001 was released yesterday, which fixes the segfault bug in 3.0000.

Hi

tried DBD-mysql-3.0001_2 (with DBI 1.48)
make gives following error:

make: *** [dbdimp.o] Error 1

Same error with DBD-mysql-3.0001

:/

Thanks

It looks like DBD::mysql 3.0001 needs MySQL 4.1.x. Use DBD::mysql 2.9008 or 7 if you're using a lower version.

[edit]It's actually a bug in the 3.0001 release - DBD::mysql should work with all versions of MySQL. The bug was fixed in the 3.0001_3 developer release.[/edit]

Hi

Pretty much suspected that so contacted the author again with details of OS and mysql (4.0.24) and here is the reply:

===
Please get the latest Dev release (3.0001_3) , which I'll send out a notice for in the morning (after mirrors have been sufficiently updated), from CPAN. .

Given the one line of information you've given, I'm not sure if this is the particular error that the latest release fixes. As well, I haven't had any bugs logged on bugs.mysql.com or in the users mailing list, so I have no information to go off of. Could you please tell me which forums?
====

Would try out 3.0000_3 sometime tonight and see if it fixes ... if not then Mysql upgrade in the offing but not interested in upgrade really at this stage

Thanks
