I *think* it's fixed ... certainly looks right for me now.  I'll leave it 24 hours to see if I get any more reports and if not consider it closed.

OK - issue sorted.

Members are allowed to attach files of certain types (such as .jpg images and .pdf documents) to their posts, subject to a maximum file size.  When displayed on the bottom of a post for the first time, certain of these file types generate a thumbnail so readers can quickly have an idea of what's in the file before they download it.  This thumbnailing process can have rather a large server memory requirement - especially when it's a large .jpf file involved.

The other day, a .jpg was uploaded which was within the maximum file size, but caused the forum software to require more than the maximum memory it's allowed when thumbnailling, causing the server request to crash "blank screen", without even an error log or message.  As the thumbnail hadn't been created, every time anyone called for the particular post to be displayed in the thread and with the attachment offered, the server tried again and crashed again.  It was, however, happy to show the post if users selected to print the thread or see it on recents, as neither of those viewing methods offers thumbnails.

The "user solution" is for me to ask members not to upload images larger than 2k x 1.5k pixels. The one the other day was over 4k x 3k.  It just contained a lot of flat grey, so the compression applied in the .jpg algorithm in the user's camera had resulted in quite a small file that had passed the server's file size limit test.

I could - but won't - limit the file upload size; the maximum is set where it is for other documents and all I would be doing is fixing one very rare problem and in the process creating a limit that would frustrate more often.  If it happens again (once in 12 years so far), please let me know - it's easy for me to resize the rogue image now that I know what I'm looking for.

Thanks Graham, All working for me now. I was confused as I was sure that I had looked at that page before without problems.

Just an alert that I'm doing some big backups and tidies ... you may see some drop in performance over the next few hours (and you may have noticed we were offline for a short while - sorry about that)

OK ... done.  41 Gbyte download ... major occasional backup, including the stuff that hardly ever changes  but needs "checkpointing" from time to time.

Server offline (unannounced and unplanned) for a couple of hours during the night - sorry.  I know what happened / straightforward to bring back up.

I am "playing" with some server settings ... a game of balancing buffers. Be aware that server may be down (for a few minutes) and back up on occasions over the next day of two. If you're writing LONG posts ... good idea to copy and paste a backup to your local machine just in case before you submit.

Sorry about the outage what was (now) late yesterday evening.  Up and running again - this is a test post to check it's working again as well as an apology.

We had a major server crash in the early hours

I am in the process of recovering and testing ... all postings to the backup at 22:30 last night should be recovered.

Anything you posted after that backup may have been lost - sorry. I am going to try to sort through the crash debris, but more in hope than expectation.  I am NOT going to look back for personal messages after the backup point for privacy reasons.

Please keep local copies of anything you post for the next few hours (always a good thing to do with major posts anyway!)

...

There is a significant risk in the installation of a tool I would need to use to look into the debris so discretion has me leaving things alone;  the system restored to 22:30 - posts, personal messages, likes, logs of what's new for you after that point to somewhat after midnight won't be back.
