call procedure error

Hi experts,

My HANA version is SPS09. When I call a procedure in HANA Studio, the following error:

Could not execute 'call "housePool.procedures::pro_fuzzyHouse"('800','b85c529b696a431da18906560978c557','east city',?,?)' in 15.237 seconds . Data receive failed [Connection reset].

But when I call the same procedure in WEB IDE, the following error:

(SQL Editor) (dberror) 129 - transaction rolled back by an internal error: statement snapshot set failed: access failure to 127.0.0.1:30003

What should I do?

Thanks.

BR,
