No idea on how I could get that on IOS

[alerque]

I'm seeing this error trying to connect a (Linux) sync client on a new machine to an existing account on a Linux ownCloud server. It gets a ways through the process of looking for what to sync and them bombs out.

[sprnza]

I've got the same issue, don't know what causes it.

[tfmm]

I can confirm this. Issue appeared for me when updating PHP-FPM and related packages from 7.0.5 to 7.0.6 on CentOS 7. Downgrading back to 7.0.5 resolved the issue.

Edit: this is using the Remi PHP7 Repo.

[alerque]

My error went away when I upgraded the ownCloud server from sqllite to mysql and added redis as a memory cache. I don't know if this is direct (e.g. an error that is only in the sqlite code somewhere) or secondary (e.g. some sort of race condition and redis is fast enough I'm not hitting it any more) but the correlation is pretty solid. I was getting the error on every sync operation for weeks, then upgraded the above two items and now for a week all my syncs have succeed.

[tfmm]

I've always used a MySQL backend. I currently have no caching setup, redis or otherwise. When I updated PHP to 7.0.6 I was unable to login at all.

[JoshHarmon]

Edit:: Applying https://github.com/owncloud/core/pull/24343/files appears to have resolved my problems.

I am experiencing the same issues as @tfmm. Upgraded from PHP 7.0.5 to 7.0.6 from ondrej's PPA and have observed the following behavior:

1. Little to no information is reaching the log, even at the DEBUG level. Only cronjob completions reached the file. No user login events or anything reached the file.
2. All DAV resources are returning 404s to clients.
3. I am unable to log in, and am immediately redirected back to the same URI with a login page and no displayed error messages.

I still see this in 9.0.2:

@LukasReschke any thoughts?

[alerque]

@tfmm and @JoshHarmon, you guys have a different issue than the one listed here, see #24343 for information on the issues caused by PHP upgrade.

[JoshHarmon]

@alerque Noticed that once someone linked me to that PR, as I noted in my comment! I assumed it was related just because of the PHP version involved, but evidently that was not a correct assumption.
