Use of unitialized values

I do get the following warning/error message when executing

Use of uninitialized value in lc at /usr/local/icinga/path/check_sansymphony line 373.
Use of uninitialized value in pattern match (m//) at /usr/local/icinga/path/check_sansymphony line 565.

...

Afterwards it continues with sane output.
