The rails file cache is something that keeps growing.
Here are some 'handy' snippets.
Delete all files older then 7 days. (replace -delete with -print to test it)
find ./tmp/cache/ -type f -mtime +7 -delete
Delete all empty folders. (mindepth prevents the deletion of the root folder)
find ./tmp/cache/ -type d -empty -delete -mindepth 1
whenever.rb I use
job_type :command_in_path, "cd :path && :task :output"
every :day, at: "0:40" do
command_in_path "find ./tmp/cache/ -type f -mtime +7 -delete"
every :day, at: "1:10" do
command_in_path "find ./tmp/cache/ -type d -empty -delete -mindepth 1"
My FreeBSD server is giving a lot of swap errors. Every day the daily reporting email was filled with kernel messages like these:
my.server.com kernel log messages:
... and many more ...
After figuring out which process was causing this, it seemed MySQL was to blame.
That was odd, because these are the number of mysqltuner is reporting about my configuration:
[--] Physical Memory : 8.0G
[--] Max MySQL memory : 845.4M
Max 850 MB
After a lot of googling, reading MySQL, it seemd the performance schema could be to blame. Because is is completely stored in memory.
Now for several days in a row, I don't have the swaperrors ☺️
To disable the MySQL permance schema place the following in
performance_schema = 0
Btw. I'm not sure if I need the performance scheme ..
⚠️ Followup a few weeks later
Unfortunately this isn't the solution. MySQL is still running out of swap space. I simply don't get it, because the memory usage should be limited
The following commands can be used to change time zone.
When the file /etc/wall_chmos_clock exists, it wil interpret the chmod time as local time.
Else it interprets the systemtime as UTC time
cp /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
Today I had an issue that I needed to resend quarantined emails.
You can simply execute the following command to inject the mails to postfix
sendmail -t < name_of_the_raw_email_file
