Error message in apache error.log

I’m getting a huge number of this error in the logs

Any Error Messages


(8)Exec format error: AH00088: exec of '/usr/sbin/sympl-web-logger' failed


  • Sympl Version [9.0/10.0]: 10
  • Sympl Testing Version? [Yes/No] yes
  • Debian Version [Buster/Stretch]: buster
  • Hardware Type? [Dedicated/Virtual/Pi] Pi
  • Hosted On? [name of hosting co] local network

The sympl-web-logger is piped the log lines from Apache, and then writes them to the relevant log, but it sounds like it’s not executable (or not there)?

If you run stat /usr/sbin/sympl-web-logger and dpkg -l sympl* what output do you get?

This is what I got:

Note the iF on sympl-web

So I decided that maybe there was a misconfiguration somewhere, so I got out a fresh microSD card and installed Debian Buster and then Sympl testing from scratch.

Now I get the same from the first test, and now all is well with the second, including the line:
ii sympl-web 10.0.191216.0 all Tools to manage Apache virtual hosting in Sympl

Unfortunately, that has not fixed the problem. The error log is still full of lines that say
AH00106: piped log program ’ /usr/sbin/sympl-web-logger -l ssl_access.log /var/log/apache2/zz-mass-hosting.ssl_access.log’ failed unexpectedly

This is a virgin install of Sympl -testing, with only a couple of hostnames added under /srv/

By the way, the public/logs directories were created automatically, and ssl_access.log is being populated as I’d expect.
Of course, in raspberrpi.localdomain the public/logs/ssl_error.log is filled instead, with stuff like

[Tue Apr 21 19:07:29.793000 2020] [ssl:error] [pid 585] AH02217: ssl_stapling_init_cert: can’t retrieve issuer certificate! [subject: CN=raspberrypi.localdomain / issuer: CN=raspberrypi.localdomain / serial: 5E9F307C / notbefore: Apr 21 17:42:20 2020 GMT / notafter: Apr 21 17:42:20 2021 GMT]

I’ve investigated, and it looks sympl-web-logger (which is compiled Go) isn’t being built seperately for armhf systems, so it only affects Raspberry Pi’s.

Here’s a quick workaround to compile it for the Pi, at which point it should stop throwing errors and work normally.

sudo su -
apt -y install git golang
cd ~
git clone
cd sympl/web
go build sympl-web-logger.go
cp sympl-web-logger /usr/sbin/sympl-web-logger

Alternatively, you can run sudo a2dissite zz-mass-hosting*; service apache2 reload which will disable the default site and mass hosting configuration.

I’ll log an issue now and should be able to push updated packages in the next day or so.

That seems to have fixed it, thanks.

I suspect this should be a fairly quick fix - it looks like SSL Stapling is enabled for self-signed certs when it shouldn’t be, so I’ve logged an issue to investigate properly.

Both of these are now fixed in stable and testing, with updated logic for SSL Stapling (which resolves the log issue), and proper packages for armhf (which fixes the sympl-web-logger issue).

@hairydog: You should be able to run sympl update now to update the package for a more permanent fix.

Splendid! Many thanks.
