Re: [ic] Payment module problems

Hi All,

We've recently moved a fairly busy catalog to a new dedicated server, and we've started to see payment module errors (resulting in duplicate charges) several times a day.

Previous server was running IC 4.9.7 (with lots of patches) on Redhat 7.2 - perl 5.6.1, mod_perl 1.26, apache 1.3.27 and a 2.4 uniprocessor kernel.

New server is running IC 5.2 on Debian 3.1 (Sarge) - (local) perl 5.8.7, apache 2.0.54 (no mod_perl) and a 2.6 SMP kernel on a single Xeon processor (Hyperthreaded).

Each time the error occurs, the debug logging that's been set up shows a "500 read error" from LWP, so IC thinks the payment has failed when in fact it has gone through sucessfully.

I was recommended to set the "PERL_SIGNALS" environment variable to unsafe, which is backed up by several other posts that I've read, but although this seems to have reduced the incidence of the problem, we're still getting one or two failures a day.

So I've just set the server to run in RPC mode (previously low traffic mode) to see if this fixes it, but I'm wondering if anyone might have an explaination and maybe a better solution?

Thanks,

One trick a client I had with many high volume stores that worked for him, was puttine an entry in the /etc/hosts file for Authorizenets server. It seems for this client the DNS lookup was causing enough of a delay at times to cause this problem. If this doesn't solve it, let me know. I had another setting for Net::SSleay that seemed to help for another client. I'll have to look through my notes to remember what that was if the hosts file entry doesn't do the trick for you.
