"500" Status: Internal Server Error in apachesolr_cron
Wednesday, July 8, 2009 - 9:23am - Kurt Vanderwater
We have installed a 'solr' server for the use of our Drupal sites. It has been an interesting experience so far. Many thanks to all who have blazed the trail ahead of us.
I started getting the error
"500" Status: Internal Server Error in apachesolr_cron
on our main testing Drupal site recently. The error was showing up in Adminstration -> Reports -> Recent log entries. I ran a few google searches and didn't find an answer. The index on this system is on the order of about 100K nodes. We had done some updates that required a 'rebuild' of the index. The error started to show up late into the rebuild process.
Well, I was looking in the wrong place. The 500 error was NOT coming from our Drupal server. It was coming from the Solr server. Something that just wasn't obvious from the error message that I could see.
Anyway, turned out that the error was very simple. The 'rebuild' of the index ran the system out of disk space. I killed off some old logs and all the RPMs that were used to install the solr system, and that provided enough space for the rebuild to finish and the old index to be removed.
All is well again, but , for all the Google searching I did on this error, and the lack of response, I thought it would be a good thing to share what fixed it for me.
Enjoy
Kurt

Firstly, I want to thank you for the useful and informative entry. I am so glad that I have found this your post. The information which you have shared for us is really good explained.

You can set the variable

You can set the variable 'apachesolr_cron_limit' in settings.php to up the number indexed per cron run, but indeed something like the above ought to work in a custom script that bootstraps Drupal. Be careful that $base_url is set correcetly, however. However - if you are using our config files you may want to substantially increase the auto commit max docs in solrconfig.xml - we have it at 500. i.e. Solr will commit right away if there are more than 500 docs pending. best electric fence

Hi all, this is for your information. Please contact me if you experience the same problem.My website is hosted at Strato (Germany). Since the beginning of January, me and several other drupal administrators experience problems with cron (it hangs) on different drupal installations, all hosted at Strato (using different hositing packages). Cron runs normally, if update-status is disabled. Klicking admin/reports/updates always shows HTTP error 500 (internal server error). Some people can't even reach their installations' admin-pages...

The following is a list of HyperText Transfer Protocol (HTTP) response status codes. This includes codes from IETF internet standards as well as unstandardised RFCs, other specifications and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; the bare minimum for an HTTP client is that it recognises these five classes. Microsoft IIS may use additional decimal sub-codes to provide more specific information,[1] but these are not listed here. The phrases used are the standard examples, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard.

Recovery
Submitted by Rugger (not verified) on June 22, 2011 - 8:43am.
When this happens to my clients I get phone calls in the middle of the night. I am now trying to integrate auto recovery software like that provided by datanumen to allow my clients to restore there own sites. Most of the sites I build are data driven sites and can be easily rebuilt by restoring a previous build. Automating and simplying this for client self-service is another matter all together though. I think I am getting close, but I stll get the deer in the headlights look too often.
