I'm also running a build client with all toolchains installed and
enabled. Here's my ccache stats:

$ ccache -s
cache directory /home/buildclient/.ccache
cache hit 132887
cache miss 25804
called for link 4011
multiple source files 457
compile failed 984
preprocessor error 5
not a C/C++ file 11894
unsupported compiler option 5513
no input file 1581
files in cache 51608
cache size 174.2 Mbytes
max cache size 976.6 Mbytes

As you can see, the default cache size limit is barely a gigabyte, so
you must have increased that at some point. If you need the space for
other things, just set the limit to something lower again:
$ ccache -M 1G

Remember that you need to do this as the user that's running the build
