Question: Warning, solutions may have been lost Help!!

Hi ,everyone.I have the following eqations I need to solve.However when I tried to run it in Maple it give out the message as shown in title.could any one see this and give some suggestions pls.

eq1 := (q/a)^2+2*q1*f*cosh(-3*p*q2/(2*a))-1-q1^2*f^2 = 0;

eq2 :=  q=a*q1*f*sinh((3/2)*p*q2/a)*q2;


solve({eq1, eq2}, {q1,q2});


Please Wait...
