Description

When I start a php script in the cloud (with jstart) I get the following error:

PHP Warning: PHP Startup: Unable to load dynamic library 'redis.so' (tried: /usr/lib/php/20170718/redis.so (/usr/lib/php/20170718/redis.so: undefined symbol: igbinary_serialize), /usr/lib/php/20170718/redis.so.so (/usr/lib/php/20170718/redis.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Testscript named tst.php is like the following:

<?php
  print strftime("%B", mktime(12, 0, 0, 1, 10, 2000)) . "\n";
?>

I start it with jsub -quiet -N tst -once -mem 750m php ~/tst.php

and after a while I see the waring message from above in tst.err

No such message appears when I run that script locally on tools-sgebastion-08

Seems to happen at least on tools-sgeexec-0951 (does not happen on a lot of other machines in the cloud)

Happens also on tools-sgeexec-0952

php-igbinary versions seem to differ across exec nodes on a quick check.

I'm willing to bet this relates to stretch backports issues (since a version clearly went away). However, it looks like the right fix is to move to the component repo version and intentionally installing the package rather than going with a dependency install.

That looks a lot better.

Yes, looks fine. I do not see that error message now. Thank you!
