DBopen error

[nlamirault]

I try the Sybase exporter like that :

$ DATA_SOURCE_NAME="compatibility_mode=sybase;user=sybase_exporter;pwd=password;server=0.0.0.0:5000" ./dbms_exporter-0.1.0.linux-amd64/dbms_exporter -driver sybase -queryfile /etc/sybase.yaml
INFO[0000] Error opening connection to freetds database: dbopen error
Msg 20010, Level 8
Unable to allocate sufficient memory (0.0.0.0:5000)

  source="dbms_exporter.go:429"
INFO[0000] Starting Server: :9113                        source="dbms_exporter.go:511"

I've got an error on database. On the instance i use isql to connect :

$ isql -Usybase_exporter -Ppassword -SMYSERVERNAME

With options :

-S server_name       Specifies the name of the Adaptive Server to which to connect to.

Any idea how to fix that ? Thanks.

I don't know, maybe it's related to #9? Try with -persistent.connection=true.

I've got this error with the new parameter persistent.connection :

you might want to try to compile the binary by yourself, we ran into the same problem, but after compiling the error was gone (could not compile static, but that's another problem)
