File upload stuck/no response if file is larger than 127KB

Added by Oliver Haucke about 1 month ago

Hey there,
i'm currently having issues uploading files to Redmine that are larger than 127KB.

$ freebsd-version
14.1-RELEASE-p5

$ pkg version -v | grep apache
apache24-2.4.62
rubygem-passenger-apache-6.0.23

Environment:
  Redmine version                5.1.3.stable
  Ruby version                   3.2.5-p208 (2024-07-26) [amd64-freebsd14]
  Rails version                  6.1.7.8
  Environment                    production
  Database adapter               Mysql2
  Mailer queue                   ActiveJob::QueueAdapters::AsyncAdapter
  Mailer delivery                sendmail
Redmine settings:
  Redmine theme                  Default
SCM:
  Git                            2.46.2
  Filesystem
Redmine plugins:
  no plugin installed

Last time, i uploaded a larger file (6MB) was 2024-09-12 14:30:19.

After a bit of debugging, i figured out that if the file is 127KB or smaller, everything is fine but as soon as the file is 128KB or larger, i do not get any response from the server/the connection timed out.

What i can confirm via setting the LogLevel of apache to trace2 (and 5) + i ran tcpdump on the server:
The HTTP connection gets established and the data are received by the server

apache trace5

Next thing i checked was the passenger log (i increased the PassengerLogLevel to 5/debug):

[ D 2024-10-09 20:28:26.0255 33442/Th Ser/Server.h:880 ]: [ServerThr.5] 1 new client(s) accepted; there are now 1 active client(s)

Looks like passenger also gets the request

Next thing i tested was config.log_level = :debug in config/additional_environment.rb but nothing related to the request got written in the log.

Just for my sanity (since i also have php available on the server), i tested the same request to a test script and there everything worked fine.

Any idea what could cause the issue or what i can test next to figure it out and solve it?

Regards

Many hours later: it looks like a problem with passenger.
If i run `bundle exec rails server -e production` everything works fine
